Abstract

PURPOSE: To provide the subject method of using an electron beam welding process or a laser welding process of high efficiency and high quality in firmly fixing a rotor conductor to end rings, thereby to achieve the accurate fixture of both parts.
CONSTITUTION: In depositing and fixing a rotor conductor rod to end rings, the leading end of the rotor conductor rod 4 is inserted in the groove of an end ring11 the groove of which has been processed, and thereafter the side surface of anend ring 12 the groove of which is not processed is joined to the end surface of therotor conductor rod 4 and the side surface of the end ring 11, the joined parts being continuously deposited and fixed by means of electron beam welding or laserwelding. For this reason, it becomes possible to apply an electron beam welding processor a laser welding process of high efficiency and high quality, and the fixture of the rotor conductor rod to the end rings becomes accurate, and therefore the quality of the rotor is improved
